VALVE-FOR NON-REHLLABLE BOTTLES,

APPLICATION FILED MAR. I8, 1915.

i 9 1 61 ,69 Q Patented Nov. 23, 1915.

@ttomvnsa further provided with a solid bottom 23 having downwardly and outwardly inclining outlet openings 24 near its peripheral edge, said bottom being provided with a cylindrical depending portion 25 whose lower end terminates in a tubular flange 26 surroundingthe neck 8 and having its lower edge disposed an appropriate distance above the partition 5. By so constructing the guard member 20, it will be evident that it is impossible to open the valve 12 from the exterior of the bottle.

In applying bottles of the class above described, to use, they are first filled with the fluid to be marketed, after which the partition is wedged in position upon the rinnf and may if desired, be cemented to this ring, the guard member is then disposed within the neck '2 and cemented or otherwise secured therein, and finally a cork (l or the equivalent thereof, is used for sealing the upper end of the bottle neck until it be delivered to the consumer. When the cork C is removed, however, and the bottle is tilted to the necessary extent, the weight of the fluid within the bottle will force the valve 1.2 open, thus allowing" such fluid to be readily discharged. It is essential, howyer. that the partition '5 be provided with an air vent 5 for allowing air to enter the bottle as the fluid is discharged therefrom. T his Vent, however, is of a size which will readily allow air to enter the bottle but through which fluid cannot travel.

By actual tests, it has been proven that an emptied bottle constructed in the manner above described, may be immersed in fluid in a number of positions, and that the same will not be filled with such fluid. Furthern'iore, jarring, of the bottle which causes a number of those now on the market to admit the fluid, will not accomplish this end when the device is constructed in accordance with my invention. It will thus be seen that I have provided a very simple and efficient non-refillable bottle which may be totally constructed of glass, with the exception of the valve 12. In manufacturing the latter,

I preferably employ mica since it possesses more resiliency than similar materials, but it will be evident that should any material be discovered which would operate to equal advantage for this purpose, it could well be used withou departing from or sacrificing any of the advantages of the invention as set forth in the following which. I claim to be the novel features thereof.

1 claim l. A valve comprising a seat member formed of frangible material and having a flat seat, a flexible non-fusible valve disk resting on said seat, and a gripping flange formeo integrally with the seat member and bent aroundone edge of the disk to anchor the latter with respect to the seat.

The method of securing a flexible non fusible valve dish. to a frangible seat member having a flat scat, consisting in forming a gripping flange integrally with said seat member adjacent the seat, and in then heatsaid flan! and bending it around one edge of the disk, whereby, when said flange cools, it will. remain in contact with the edge of the disk and will eii'ectively anchor the latter.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
